A non-government organisation in the autonomous Papua New Guinea province of Bougainville says more and more people want to move off the flood-threatened Carteret Islands.
The tiny islands are regularly inundated by sea water, compromising the islanders' living conditions.
The NGO, Tulele Peisa, has for several years been working to relocate families to the Bougainville mainland at Tinputz.
So far six families have moved but spokesperson for Tulele Peisa, Ursula Rakova, says their aim is to accommodate 1,700 people by 2020 at four different sites.
She says there is now a lot less reluctance to leave the Carterets.
"Right now there are more and more people willing to sign up to move to mainland Bougainville because of the lack of sufficient food that can be grown on the islands, the population is also increasing, the land is getting shorter and basically not available land suitable for growing a lot of food crops."
